Publication protocol

Total protein was isolated from cells by the RIPA buffer. Protein concentration was determined by the BCA (Pierce). Twenty micrograms of total proteins were resolved using the NuPAGE precast gels (Invitrogen) and transferred to polyvinylidene difluoride membrane. Following blocking with 5% BSA in TBS-T, the membrane was incubated with primary antibodies and secondary antibodies. Immunoreactivity was detected using Amersham ECL Prime (GE). The immunoblots shown represent the results of least three independent experiments (Supplementary Fig. 11). Protein density was measured with ImageJ.

Tissue samples were collected and snap-frozen in isopentane (VWR) liquid nitrogen slurry. For caspase 3 and TUNEL staining, limbs were placed in 4% formaldehyde for 1 h before being frozen. Sections (6–8 μm) were thawed at room temperature and fixed in 4% formaldehyde for 5 min. Sections were blocked with 10% donkey serum in 0.1% Triton-X for 30 min at room temperature. Sections were incubated with a relevant primary antibody overnight at 4 °C and with secondary antibodies for 1 h at room temperature. Antibodies were diluted in blocking buffer and sections were mounted in mounting medium (DakoCytomation) containing 5 μg ml−1 4,6-diamidino-2-phenylindole (Sigma). Myoblasts and myotubes were fixed with 4% formaldehyde or ice-cold methanol for 5 min. Cultured cells were permeablized with 0.5% triton-X for 10 min and blocked with 10% donkey serum, and follow the same staining procedure as tissue sections.
